Letters Patent No. 106,867, dated August 30, 1870.

IMPROVEMENT IN OPERATING- VALVES..

The Schedule referred to in these Letters Patent and making part of the sarde.

To all whom it may concern Be it known that I, ABRAHAM L. PENNocK, of Upper Darby, in the county of Delaware and State of Pennsylvania, have invented anew and useful Improvemeut in Operating Valves; and I do hereby' declare vthat the following is a. full, clear, and exact description thereof, which will enable others skilled' in'the art to make and use the same, referencebeing had to the accompanying drawing forming part of this specification.

This` invention relates to a new and useful im provement iu operating valves, whereby they may be arranged in short tubes of small diameter, and removedv valve. Y

Similar letters of reference indicate corresponding parts. y

A represents the tube in which 'the valve is placed. B is the valve.Y C is the valve-stem. Dis the valve-seat. The seat is an oval'plate with au oval orilce placed at au angle of forty-five degrees,more or less, iu the l tube, as represented in the drawing.

Opposite the valve-seat a slot or opening is made,

through the tube, around the edge of which' there is" a ange, E, tightly tted and soldered to the tune, to which flange a covering-plate, F, is fitted.

Attached to this plate is the nut G of the screw valve-stem.

On the back of the valve there is a socket, H, and on the end of the valve-stein there is a ball, I, which engages .with thc. Socket;

J is a slot in the socket, which allows the valve to rise from its Aseat when the stem is unscrewed.

K is au arm, which is hinged to the valve at one end, to the plow F at the other end.

' This hinged arln guides the -valveand keeps it in the right position in opening and closing.

By this arrangement the valve may be drawn back or opened so as to leave the tube nearly unobstructed.

The plate-F is fastened on by screws, so that it may be taken o" and the valveremoved at pleasure.

' L is a hand-wheel ou the valve-stem for operating the valve.

VBy hanging the valve and operatingvit in this mauner, it is Inadeto work Vin a shorter tube than it could if it were lifted perpendicularly from its seat.

Having thus described my'iuvention,

I claim as new and desire to secure by Letters Patent- The flanged tube A E, valve-seat D, valve B H, stem C, and covering-plate 14", combined, constructed, and relatively arranged, as and for the purpose described.
